Official recommendations from professional societies

ASRM (USA): Planned oocyte cryopreservation is an emerging but ethically permissible procedure that may help women avoid future infertility.

FertiPROTEKT (Germany, Austria and Switzerland): Patients who are of age at the time of cryopreservation must be given individual advice and information about the higher chances of success before the age of 35.

The Society of Obstetricians and Gynaecologists of Canada: Social egg freezing is an increasingly common method for women to attempt to guard against natural age-related fertility decline. Although existing data is limited, it demonstrates an acceptable pregnancy rate, as well as some psychosocial benefit.
